SYSTEM OF GAR-SIGNALING FOR GRADE-CBOSSINGS.

To all whom it may concern Be it known that I, WALTER N. JOHNSON, a citizen of the United States, residing at lVilliamsport. in the county of Lycoming and State of Pennsylvania, have Invented new and useful Improvements in Systems of Car-Snznalin; for Grade-Crossings, of which the following is a specification.

This invention relates to improvements in car signaling systems and has particular application to' a crossing signal system for electrically propelled cars.

In carrying out the present invention, it is my purpose to provide a system of car signaling for use at grade crossings and embodying electric lamps at opposite sides of the car and disposed adjacent to each end thereof and connected in series in an electric circuit, and means for closing the circuit to illuminate the lamps when the car is passing over the crossing so that the motorman or operator of a train approaching the crossing on the other line of track will be advised as to the condition of the crossing.

It is also my purpose to provide a system of car signaling of the class'described which will embrace the desired features of simplicity, eiiiciency, durability and reliability and which may be installed and maintained at a minimum expense.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts here inafter set forth in and falling Within the scope of the claim;

In the accompanying drawing; Figure 1 is a longitudinal sectional view through a car equipped with the present invention.

Fig. 2 is a diagrammatic view of the invention.

Referring now to the accompanying drawing in detail, A designates a car of any suitable or preferred construction. Upon opposite sides of the car adjacent to each end thereof and disposed immediately below the roof of the car are electric lamps 1, 1 disposed in suitable chambers or compartments formed in the sides of c the car and visible through colored bulls eyes. An electric circuit Qincludes the lamps 1, 1 in series and is supplied with current from a Specification of Letters Patent.

cuit 2 so that the circuit may be closed from either end of the car. The )ilot lamps are disposed within the vision 0: the motor-man,

.while the switches are within convenient reach of the conductor.

From the foregoing description taken in connection with the accompanying d airing, theconstruction and manner of employing my invention will be readily apparent. It will be seen that when a car is passing over a crossing and the electric power is cut off, the lamps in the car will be extinguished, while by means oi my improved system of 'ar signaling, the lamps l, 1 may be illuminated independently of the supply of power to the ('ar lamps, thereby advising the motorman oi the train or car operating over the other line. of track of the condition of the track. It will be observed that by displaying theside lights of the car or train, while such car or train is passing over the crossing, safety will be assured.

I claim:

In a system of car signaling for grade crossings, the combination with a car having chambers formed in the sides adjacent to the opposite ends thereof, of electric lamps disposed within said chambers, a local circuit including said lamps in series, switches for closing said circuit when the car passes over a crossing whereby the side lights will be visible to the motorn'ian of a car approaching the crossing on another track, and pilot lamps connected in series in said circuit and disposed within the vestibule of the car whereby the motorman there of will be advised as to the condition of the signaling system.

In teestimony whereof I aflix my signature in presence of two witnesses.

WALTER N. JOHNSON.
